Specification of Letters Patent.

Patented Mal-.28, 1916.

Application filed May 29, 1913. Serial No.- 770,597;

To all whom it may concern:

Be it known that I, JOHN F. HATFIELD, a citizen of the United States, residing at My invention relates to improvements in containers and it specially appertains to the features pointed out in the annexed claim. 4

The purpose of my invention is to provide a receptacle body that shall give the maximum strength with a minimum weight; that shall retain its shape under all kinds of hard usage; that shall have resiliency so as to avoid fractures through accidental or other contingencies. In short to form a receptacle that is-reinforced by laminations which are placed at' diflerent angles with respect to each other, and which is economical in theuseof material as well as simple to make,

thus affording the greatest durability, least transportation charges in shipment and the largest economy in construction. With theseends 1n view I show such an instance of adaptation in the accompanying drawing as will disclose the broad features underlying the inventionwitho-ut limiting myself to the specific details shown.

- Figure 1. illustrates a' blank for the outer shell. Fig. 2. is a similar view of a blank f r the inner portion of the receptacle body. Fig. 3. is a perspective of the outer shell bent in shape ready for assembling. Fig. 4.

y is a perspective of the inner shell bent in shape ready for assembling. Fig. 5. is a perspective of the inner and outer parts assembled. Fig. 6. is a cross section, showing the laminations. Fig. 7. is an enlarged corner detail, in perspective.

In making receptacle bodies, that conform to the features of my invention I may utilize so called veneer stock and cut the same to the approximate shapes shown in Figs. 1 and 2.

The outer shell is bent up from a sheet A that has four V shaped notches. a, cut in its edge, facing the sides of the sheet, supplemental notches. a, are formed at the four points when thick material is used where the bends will intersect with "each other. The bending is done on center lines S S and E E. These lines are practically cento the material.

tral of the rounded corners which are formed 1n the bending operation so as to make it easier to produce a trunk or other body and also secure greater strength. The

blank and on the ends of the inner blank,

the continuous or uncut portion of one blank reinforced the jointed edges of the other one. This expedient breaks joints and forms a very solid type of construction. When both blanks are bent up in a hydraulic press, the inside face of the outer shell and the outside face of the inner shell are covered with glue or other adhesive and placed the one within the other. this relation while subjected to pressure in a suitable press having dies that conform to ,the shape and cross section of the shells. By combining the laminations as described the edges of the V shaped notches, substantially meet each other so as to practically form a jointless receptacle which has been subjected to the least distorting stresses They" are held in produced. It is however immaterial how r the notches, a, are .formed so long as the material is relieved at thepoint where the three-faced bends are made. This permits the cellular material to flow smoothly and thereby the formation of wrinkles, etc.. is avoided." If such a body is used as a lid. for a container as well as the body of the same it would of course be considered as an equivalent thereof. i

It should be understood that I dov not limit myself to the s ecific details shown,

as many modifications can be made without departing from the spirit of my invention. The sides may be made sloping or perpendicular. If sloping, corners may be reinforced with an extra piece or pieces placed inside or outside or'both as desired. Sloping structures admit of easy nesting for conveniences in shipping, etc. The unit sheets may be discontinuous in either direction providing that when a plurality of sheets are united the contiguous edges of the sections of the one unit will be out of register with those of the adjoining unit.

What I claim is, An article of manufacture, comprising a composite receptacle of laminated structure formed of independent inner and outer bent up blanks, one of the blanks having two opposite edges indented with large V shaped incisions joined to small notches formed at the point of the V and its other edges plain, the other blank having similarly shaped edges, each blank being bent indentations of one blank are held against the plain edges of the other blank and the small notches connect with each other forming openings at their respective corners extending into the three adjacent faces, and having suitable corner plates adapted to cover such openings.

In testimony whereof I aflix my signa-e ture in presence of two witnesses.

JOHN F. HATFIELD.
